Exceedingly Large Cubic Zeeman Terms for a High Spin Cobalt(II) Complex Originated from the Substantial Unquenched Orbital Angular Momentum

Key Points

• This research aims to explore the cubic Zeeman terms in high spin cobalt(II) complexes and their relation to orbital angular momentum.
• Analyzed the orbital angular momentum contributions in cobalt(II) complexes.
• Utilized quantum mechanical models to predict the behavior of states with orbital near-degeneracies.
• Observed exceedingly large cubic Zeeman terms in the studied cobalt(II) complex, indicating strong influence of unquenched orbital angular momentum.
